On a moonless night on Sanibel Island, Florida, marine biologist Marion "Doc" Ford carefully watches a video of a hooded man executing three hostages. The man is an American working with ISIS, and in the next few days, it'll be Ford's job, as part of his shadowy second life, to make sure he never kills anybody else again.
